Definitions

  • the present invention refers to a permanent-magnets mono-phase synchronous electric motor with improved stator structure, in particular for discharge pumps of washing machines and similar household appliances.
  • the invention regards a motor of the aforementioned type and comprising a central permanent-magnetic rotor, a stator with a lamination pack core and a couple of pole pieces enveloping said rotor, of which they have substantially the same axial length.
  • the rotor should reach the synchronism speed in a period of time equal to half the network wave period. This however is extremely difficult, in particular if the motor has a significant moment of inertia and must contrast the torque of a load associated with the rotor.
  • the synchronous electric motor is equipped with an electronic start-up device which allows the gradual starting of the motor by applying the current and voltage vectors to the stator windings with appropriate phase shifts.
  • the position of the rotor is also detected by means of a position sensor which transmits the information to the electronic monitoring device, which decides whether or not to apply the electrical power to the stator windings, through a power switch, depending on the polarity of the electrical power source in each given instant, thus generating the most appropriate magnetic flux for the start-up step.
  • This flux interacting with the magnetic flux generated by the rotor, produces a torque capable of accelerating the rotor in a specific rotation direction until the synchronism speed with the electrical supply source is reached and maintained.
  • This stator structure enjoys the advantage of being simple to realise and of relatively low cost. Nevertheless, the present needs to limit production costs make also the mono-phase synchronous pumps realised with this stator structure surprisingly expensive.
  • the technical problem underlying the present invention is that of devising a permanent-magnets synchronous electric motor, in particular for discharge pumps of washing machines, having such structural and functional characteristics as to allow an easy start-up together with a structure of particular simplicity which allows its manufacturing at considerably lower costs than the solutions presently proposed by the prior art.
  • the solution idea underlying the present invention is that of providing the assembly of the stator group core by means of a lamination pack having axial length shorter than the axial length of the corresponding ends of the pole pieces.
  • such ends of the pole pieces are associated with the lamination pack in a removable or in any case structurally independent way.
  • said ends of the pole pieces are realised through moulding starting from magnetic powders microencapsulated by electrically insulating substances.
  • 7 globally and schematically indicates a mono-phase synchronous electric motor realised in accordance with the present invention for the operation of a synchronous discharge pump 1 to be mounted preferably on washing machines such as washing machines and dishwashers, not shown in the drawings since they are of conventional type.
  • the motor 7 has a permanent-magnets central rotor 2 and a stator 4 comprising a lamination pack core 5 with a couple of pole pieces 10, 11, enveloping the rotor 2 and from which they are spaced by respective airgap.
  • the rotor 2 has a longitudinal axis x-x which coincides with the axis of a rotation shaft 3 which is supported by opposite bearings 13, 14.
  • the rotor 2 is tightly insulated with respect to the stator 4 by an essentially tube-shaped envelope 17 integrally formed with a flange-like portion 6 intended to be coupled on one side with a volute , not represented since conventional, of the pump 1 and on the other side with a envelope 12 covering the stator 4 of the pump 1.
  • the motor 7 is intended to activate the operating gear, i.e. an impeller 9 enclosed within the coil of the pump 1.
  • the coupling between the impeller and the end of the driving shaft 3 is obtained by means of a kinematic joint 8, for example as described in the European Patents No. 0 287 984 and No. 0 983 630 to the same Applicant.
  • the motor 1 comprises a stator 4, with related lamination pack core 5 and stator windings 18, 19, as well as ends 10, 11 of stator pole pieces.
  • the stator 4 conventionally comprises a plurality of metallic laminations arranged as a pack to form the core 5 and stator windings 18, 19 adjacent to each other and having terminal ends defining two pole pieces 10, 11 being diapason-like arranged around the rotor 2.
  • the core 5 is realised with packs of cut laminations having a substantially U-like form in plan view.
  • Such laminations are obtained from a same plate band in order to reduce the production losses and they are stacked on a massive core 5 being in turn a U-like shaped.
  • stator windings 18, 19 are realised on respective coil bobbins which are then placed on the two U-shaped prongs of the lamination pack core 5 and the pole pieces thus obtained are brought close together to form a structure with ends 10 and 11 of the pole pieces enveloping the diapson-like rotor 2, as shown in figures 4A , 5A and 6A .
  • the assembly of the core 5 of the stator group is obtained by means of a pack of laminations having axial length shorter than the axial length of the corresponding ends 10, 11 of the pole pieces.
  • such ends 10, 11 of the pole pieces are associated with the lamination pack core 5 in a removable way or in any case so as to be structurally independent therefrom.
  • the ends 10, 11 of the pole pieces are associated with each corresponding end of the prongs of the U-like lamination pack core with a substantially tenon and mortize coupling.
  • the size of the core 5, whereon the stator windings 18, 19 are provided is unconstrained from the size of the pole pieces 10, 11, facing the permanent magnets of the rotor 2.
  • the aforementioned shorter axial length of the lamination pack core 5 is between 25% and 50% and preferably approximately 40% lower than that of the pole pieces 10, 11.
  • this characteristic of the present invention does not worsen the steady performances of the synchronous motor, but, above all, it does not worsen the performances at the breakaway, i.e. at the start-up step, which are the most critical aspect of this type of motors, as it will be described in greater detail hereafter.
  • Figures 4 , 5 and 6 well show the coupling modes between the ends 10, 11, obtained through moulding of the stator pole pieces, and the corresponding ends of the prongs of the U-like lamination pack core 5.
  • figure 5 shows an embodiment wherein the ends 21 and 22 of the two prongs of the U-like lamination pack core 5 have respective mortise slots 25, 26, or alternatively dovetail-like slots, to receive a corresponding tenon 29 integrally formed in each SMC element 27 or 28.
  • the conformation of the SMC elements which form the ends 10 and 11 of the pole pieces in the example of figure 5 was obtained through moulding the aforementioned magnetic powders so as to obtain a hollow portion, partially enveloping the rotor 2 and a side appendage defining the tenon 29.
  • figures 4 and 4A show a different coupling conformation between the ends 45, 46 of the prongs of the U-like lamination pack core 5 and the SMC elements which, in this example, have been indicated with numbers 47 and 48.
  • the ends 45, 46 of the prongs provide respective mortise or dovetail-like slots 41, 42 facing each other and turned towards the rotor 2.
  • Each of the SMS elements 47, 48 has instead a respective tenon appendage 43, 44 integrally formed through moulding on the opposite side with respect to the concavity turned towards the rotor 2.
  • figures 6 and 6A shows a further embodiment wherein the ends 35, 36 of the prongs of the U-like lamination pack core 5 are inclined and flared with respect to the a symmetry plane ideally passing through the rotor axis and separating the two windings 18, 19 from each other.
  • ends 35, 36 have respective mortise or dovetail-like slots 33, 34 turned towards the rotor 2.
  • Respective tenon appendages 31, 32 are provided being integrally formed through moulding in the SMS elements indicated with numbers 37 and 38 which represent in the example of figures 6 and 6A the ends 10 and 11 of the stator pole pieces.
  • the axial length of the lamination pack core 5 essentially coincides with the axial length of the tenon appendages 29, 31, 32, 43, 44 of the SMC elements, all of which, on the other hand, have a prismatic body of greater axial length.
  • the supply voltage is bound to the breakaway one according to a ratio well-defined within project specifications and normally greater than 1.1.
  • the voltage applied to the input terminals is generally distributed in a drop ⁇ Vr on the resistance of the coil Ra, a drop ⁇ Vd on the dispersion inductance Ld, i.e. linked to the whole magnetic flux which does not interconnect the rotor 2, and an electromotive force Vi on the armature reaction inductance Li related to the useful magnetic flux which interconnect the magnet and produces torque.
  • Va ⁇ Vr + ⁇ Vd + Vi
  • the motor according to the invention has the great advantage of being of an unusual structural simplicity combined with a production cost much lower than that of the current alternative solutions of the known art.
  • stator pole pieces are unconstrained from the size of the lamination pack core they are associated with.
